Quadratic Function HTML5 applet – Vertex form

An html5 applet to explore the properties of quadratic functions in vertex form. The parameters a, h and k included in the definition of a quadratic function of the form f(x)=a(x−h)2+k may be changed and therefore the graph of function f explored. We may explore the vertex, the x … Continue reading
